2004-08-08 Update

As of this date, all reporting countries in Europe are on 144.8000 MHz, in
compliance with the IARU region 1 conference in 2002, which had decided on an
APRS frequency
recommendation for Europe (PDF). Quoting Tapio Sokura oh2kku in May of 2003:

The recommended frequency is 144.800 MHz. Almost all European APRS activity
is there already, now it's also in the official bandplan.

Tapio oh2kku has sent an updates this weekend (7-8 August 2004), regarding Finland's
and Denmark's APRS usage, filling in the final pieces to the puzzle, even if the changes
actually occured in 2003... Quoting:

When setting up one APRS digipeater I remembered your pages on european
APRS frequencies. All APRS activity in Finland on 2 meters is nowadays on
144.800 MHz, so you can remove all references to 144.825 MHz being used in
Finland.

OK, so the latest word remains that most of Europe will be operating on 144.8000,
eventually. My personal recommendation, based upon the reports I've received, is to monitor
144.8000 first before setting up an APRS transmitting station. If you do not see or hear
any activity on 144.8000, try listening to 144.8125 in countries not listed above.
However, we're moving ever closer to a unified APRS frequency for Europe.

The balance of this information will be subject to change, as the new IARU
recommendations are adopted.

In addition to 144.8000 in Sweden in the 2m band, there APRS is activity on
433.8000, 14.1500, and several 6m frequencies. Additionally, there are gateways
between 2m, 20m, and 70cm bands.

While obviously not part of Europe, Australia has officially set aside
145.1750 for APRS use.

I have one report for South America, with Sao Paulo, Brazil operating on 145.7800.

Internet gateways have been established in
Southeastern U.K,
and Luxembourg on 144.8000, sending local data to the www.aprs.net internet feed. Note:
Regulations in some countries restrict rebroadcast of internet data to RF.

More as reports are given.

Pleaselet me know what frequency or frequencies you are using for APRS in your area, so that I can keep this map
updated!
